A substitute is a good or service that buyers can quickly swap out for another. For instance, a one-dollar bill can be used in place of another dollar bill.

In business and economics, a replacement, or substitutable good, is a good or service that consumers perceive as just being substantially the same as or reasonably similar to some other good. Consumers are given options and alternatives through substitutes, which also spur competition and lower prices in the market.

Here are a few examples of replacement goods:

1. A $1 bill can be exchanged for four quarters.

2. Coke against Pepsi

3. Regular vs. premium gas

Answer: V² = U² + 2as

This equation is known as the equation of motion, and it relates the final velocity (V) of an object to its initial velocity (U), acceleration (a), and displacement (s).

The equation states that the square of the final velocity is equal to the square of the initial velocity plus twice the product of acceleration and displacement.

The equation can be used to calculate the final velocity of an object if the initial velocity, acceleration, and displacement are known, or it can be used to calculate the displacement of an object if the initial velocity, final velocity, and acceleration are known.

This equation is based on the concepts of physics and it's used to calculate the velocity of an object under constant acceleration.

Step-by-step explanation:

The expression is a monomial.

The expression 5x is a monomial. A monomial is an algebraic expression that consists of one term and is not the sum or difference of other terms. It can be a constant number, a variable, or a product of a constant and one or more variables. In this case, the expression has only one term, which is the product of the constant 5 and the variable x. Therefore, it is a monomial.

A monomial is an algebraic expression that consists of one term and is not the sum or difference of other terms. It can be a constant number, a variable, or a product of a constant and one or more variables. For example, 5, x, and 3x^2 are all monomials.

A binomial is an algebraic expression that consists of two terms and is the sum or difference of those terms. The two terms can be monomials, for example, 3x+2 and 5x^2-7 are binomials.

A trinomial is an algebraic expression that consists of three terms and is the sum or difference of those terms. Like binomials, the terms can be monomials, for example, 2x^2 + 5x +7 or 3x^2 -2x -5 are trinomials.

Option D is the correct answer.

The required required value of G is 1) 2.11 × 10^7 2) 2.06 × 10^7.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

We have,

1) m = 6. 1 x 10^-5, t = 1. 7 x 10^-6

G = m/t^2

G =6. 1 x 10^-5/(1. 7 x 10^-6)^2

G = 2.11 × 10^7

2)m is increased by 8%

New m = 6.59 x 10^-5,

t is increased by 5%

New t = 1.79  x 10^-6

So

G = m/t^2

G = 6.59 x 10^-5/(1.79  x 10^-6)^2

G = 2.06 × 10^7.

Thus, required value of G is 1) 2.11 × 10^7 2) 2.06 × 10^7.

The product of AXB is the matrix C, where Cij = Σk=1nAikBkj, where n is the number of columns in A.

The product of two matrices A and B is a new matrix C, which is obtained by multiplying each of the elements of A with the corresponding elements of B. The size of the resultant matrix C will be the same as that of A and B. For example, if A is m×n and B is n×p, then the product AXB will be an m×p matrix. The value of each element of C is determined by multiplying the elements of corresponding rows of A with those of corresponding columns of B, and then summing up the products. Mathematically, the value of Cij (the element in the ith row and jth column of C) is given by the equation

Cij = Σk=1nAikBkj,

The measure (in degrees) of the smallest interior angle of a triangle in which the exterior angle measures have the ratio 4:5:6 is 36°.

The exterior angles of a triangle measure the angle between one side of a triangle and the extension of an adjacent side. The sum of the exterior angles of a triangle is always equal to 360 degrees.

In a triangle in which the exterior angle measures have the ratio 4:5:6, we can express the measures of the exterior angles as 4x, 5x, and 6x.

360 = 4x + 5x + 6x

360 = 15x

Solve for x by dividing both sides by 15:

x = 360/15 = 24

Knowing that the measures of the exterior angles are 4x, 5x, and 6x, we can find the measure of the smallest interior angle by subtracting the biggest exterior angle from 180 degrees:

biggest exterior angle = 6x = 6(24) = 144°

smallest interior angle = 180° - 144° = 36°

The equation that represents the graph is y equals negative three halves times x minus 3, and option A is correct.

The ratio of the change in y coordinate to the change in x coordinate is known as a line's slope.

y and x, respectively, stand for the net change in the y-coordinate and the net change in the x-coordinate.

Consequently, the connection between a change in y-coordinate and a change in x-coordinate

Given a graph,

from the graph, we find that when y is 0, x = -2

and when x is o, y = -3

so the line passes from (-2, 0) and (0, -3)

the slope of the line is (y₂-y₁)/(x₂-x₁)

m = (-3 - 0)/(0 - 2)

m = -3/2

and the y-intercept is -3

equation of line is y = mx + c

y = -3x/2 - 3

which is y equals negative three halves times x minus 3.

a) The probability that a person has the virus given that they have tested positive is 0.5.

b) The probability that a person does not have the virus given that they test negative is 0.9.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.

Virus infects one in every 400 people.

Let A = be the event of being infected.

Let A' = be the event of not being infected.

Let B = be the event of being tested positive.

Let B' = be the event of being tested negative.

Let the population = 1,00,000

So, now the number of infected people are -

Infected people = (1/400) 100000

Infected people = 250

The number of non-infected people are -

Non-Infected people (T') = 100000 - 250

Non-Infected people (T') = 99750

The test is 80% positive when the person has the virus -

N(A|B) = 0.80 × 250

N(A|B) = 200

So, the probability value for N(A|B) -

P(A|B) = 200/400 = 0.5

The test is 10% positive when the person does not have the virus -

N(A'|B) = 0.10 × 99750

N(A'|B) = 9975

Number of people who test negative when they don't have the virus -

N(A'|B') = (T') - N(A'|B)

N(A'|B') = 99750 - 9975

N(A'|B') = 89775

So, the probability value for N(A'|B') -

P(A'|B') = 89775/99750 = 0.9

Therefore, the probabilities are 0.5 and 0.9.

There are 9 or 10 distinct ways to arrange 6 beads of distinct colors in a 2x3 grid if reflections and rotations are considered the same. We can solve this problem using Burnside's Lemma.

Burnside's Lemma states that for a group action on a set, the number of fixed points is given by the average over the group of the number of fixed points under a particular group element, where the average is taken over all group elements.

In this case, the group action is the action of rotating and reflecting the grid, and the set is the set of all possible bead arrangements in the grid. To use Burnside's Lemma, we need to find the number of fixed points (i.e., bead arrangements that are unchanged) under each group element, and then take the average over all group elements.

There are a total of $4$ rotations and $2$ reflections possible for a 2x3 grid.

The identity transformation keeps the grid in its original position, and thus there are

6!/(2!3!) = 60

The $90 rotation keeps $3 beads in the same place and switches the other $3, and similarly $180 and $270 rotation also keeps $3 beads in the same place and switches the other $3$, thus there are

3! = 6

The reflection on the horizontal axis keeps $3 beads in the same place and switches the other $3, and similarly the reflection on the vertical axis also keeps $3 beads in the same place and switches the other $3, thus there are

3! = 6

So the average number of fixed points is $(6+6+6+60)/8 = [tex]\frac{78}{8}[/tex] = 9.75$

So, there are 9 or 10 distinct ways to arrange 6 beads of distinct colors in a 2x3 grid if reflections and rotations are considered the same.
